N7977A

The N7977A is designed for automated test equipment (ATE) applications where high-speed dynamic sourcing and measurement is needed.

Accelerate test throughput with industry-leading specifications

• Test speeds 100x faster than standard system power supplies
• Command processing speed < 2ms
• Fast up/down programming speeds up to 500 µs
• Adjustable measurement rate to balance speed and accuracy

Accurately characterise your DUT's power profile with advanced measurement capability

• Dual voltage and current measurement capability with DMM-like accuracy
• Power, peak power, watt hour, and amp hour measurements

Full two-quadrant operation for power storage test applications

• Provides continuous smooth operation between +current and - current transitions
• Provides + and - programmable current limits, programmable + and - current waveforms, and automatic down programming
• Full two-quadrant operation requires N7909A power dissipater units, standalone power supply offers 10% rated current two-quadrant operation

Track power events with a black-box recorder

• Optional accessory N7908A black-box recorder
• Works in the background tracking power events whenever the APS supply is on
• Records measurement data, trigger events, status bits, and more

Add power flexibility to your test system with built-in APS paralleling up to 10 kW

• Ensures equal current sharing among paralleled supplies
• Implemented with three wire connection on power supply rear panel
• Ensures each paralleled supply operates in its intended mode, whether that is CV or CC
